The area of the complete circle is PI x 11^2 = 379.94 cm^2

The shaded part is 30 degrees out of 360 degrees

The shaded area = 379.94 x 30/360 = 31.66 = 31.7 cm^2.

The answer is B.

A family charges a trip to the zoo on a credit card. The simple interest rate is 12%. The charges are paid after 3 months. What

vodomira [7]

The formula for simple interest is: $A = P(1 + rt)$
$R=12$
We are going to convert the percent (12) into a decimal.
$r = R/100 = 12/100 = 0.12$
Then, we are going to put the months into years.
$3 / 12 = 0.25$
Let's plug in the values:
$A = 175.54(1 + (0.12 * 0.25)) = 180.8062$
$A = 180.81$
The total amount paid for the trip is $180.81

Have a nice day! :)

If the triangles are similar, the side lengths form a proportion of that

$\frac{3}{3} = \frac{3}{3}$
